CARBURETOR OF INTERNAL COMBUSTION ENGINE Russian patent published in 2002 - IPC

FIELD: mechanical engineering; internal combustion engines. SUBSTANCE: invention relates to vaporizing carburetors for fuel systems of internal combustion engines. Proposed carburetor has float chamber, vaporizing chamber with air supply branch pipe and fuel-air mixture outlet branch pipe. Mixing chamber has air channel with choke communicating through pipeline with vaporizing chamber air supply branch pipe and fuel-air mixture channel communicating through pipeline with branch pipe through which fuel-air mixture is let out from vaporizing chamber and furnished with throttle valve. Bubbling device made in form of chamber with great number of tubes whose holes are pointed to vaporizing chamber bottom is arranged inside vaporizing chamber and is placed in communication with air channel through pipe line with check valve. Device for separating residual drops of fuel, for instance, labyrinth, is installed in vaporizing chamber over bubbling device. EFFECT: provision of complete combustion of fuel by homogenizing fuel-air mixture in carburetor, reduced consumption of fuel and toxicity of exhaust gases, provision of fire and explosion safety, improved reliability of starting at low ambient temperature. 4 cl, 2 dwg
